In the related art, a temperature sampling structure is arranged in a battery, the temperature sampling structure is used for acquiring temperature information of components such as a battery monomer in the battery, the temperature information is transmitted to a battery management system in the battery, and the battery management system analyzes and processes the operation information, so that various components in the battery are controlled to execute corresponding operation strategies to maintain normal and safe operation of the battery.
In order to facilitate assembly efficiency and convenience of subsequent overhauling, the temperature sampling structure is detachably connected with a temperature measuring position in the battery. That is, on the one hand, the temperature sampling structure and the temperature measuring position are kept fixed, so that the temperature sensor can conveniently acquire the temperature change condition of the temperature measuring position; on the other hand, the temperature sampling structure is also convenient to separate later so as to be convenient for maintenance and replacement.
Threaded fasteners are typically used to secure the temperature sampling structure in place in the battery for temperature measurement. The screw fastener can apply the moment of torsion to the temperature sampling structure at rotatory in-process that realizes the screw interlock, and then makes the temperature sampling structure produce the rotation trend of relative temperature measurement position, and then produces the effort of pulling to the temperature sampling structure, probably can cause the damage of temperature sampling structure.
Based on the technical problems, the embodiment of the utility model provides a temperature sampling structure, wherein a stop piece is arranged on a temperature sampling structural member and is used for being abutted with a temperature measuring position so as to inhibit the rotation trend of the temperature sampling structure generated in the rotation process of a threaded fastener.
In particular, referring to fig. 3, 4 and 7, an embodiment of the present utility model provides a temperature sampling structure 140, and the temperature sampling structure 140 is used to obtain temperature information of a temperature measurement location in the battery 100. Which includes a temperature sensor 10, an adapter 20, and a mount 30.
The temperature sensor 10 is used for acquiring temperature information, and refers to a sensor capable of sensing temperature change and converting a physical signal of the temperature change into an electrical signal which can be output.
The specific type of the temperature sensor 10 is not limited, such as a thermocouple sensor, a thermistor sensor, and the like.
The temperature sensor 10 can directly contact with an object to be measured, and directly acquire temperature change information of the object to be measured in a heat conduction mode; the temperature change information of the object to be measured can be indirectly obtained through other objects in contact with the object to be measured without directly contacting the object to be measured.
It should be noted that, specific principles, related structural forms, etc. of implementing sensing temperature by the different types of temperature sensors 10 are disclosed in the related art, and are not described herein.
The adapter 20 is electrically connected to the temperature sensor 10 to receive a temperature signal sent by the temperature sensor 10.
It will be appreciated that the adaptor 20 is adapted to electrically connect with a data signal receiving device such as a battery management system in the battery 100 to transmit a temperature signal of the temperature sensor 10 to the data signal receiving device.
The mounting base 30 is configured to contact the temperature measurement location, that is, at least through a heat conduction effect, the temperature of the mounting base 30 can change with a temperature change of the temperature measurement location.
The temperature sensor 10 is provided in a mounting base 30, and the mounting base 30 provides a mounting position for the temperature sensor 10.
Mount 30 includes a mount 31 and a stop 32.
The mounting member 31 is used for contacting with the temperature measuring position, and at least the temperature sensor 10 can sense the temperature change of the mounting member 31 through the heat conduction between the mounting member 31 and the temperature sensor 10, so as to indirectly acquire the temperature information change of the temperature measuring position.
The mounting member 31 is provided with a through hole 31a therethrough, and the through hole 31a is used for penetrating the threaded fastener 131.
The threaded fastener 131 refers to a connection structure provided with threads, which can be screwed with threads of other components by means of rotation.
The particular type of threaded fastener 131 is not limited, such as a stud, bolt, screw, or the like.
After a part of the threaded fastener 131 passes through the through hole 31a, it enters into the through hole 31a or the screw hole provided at the temperature measurement position, so that a part of the mounting member 31 is sandwiched between the threaded fastener 131 and the temperature measurement position, and the threaded fastener 131 is rotated to make a threaded connection between the threaded fastener 131 and the temperature measurement position or make a threaded connection with other threaded fasteners 131, thereby enabling the mount 30 to be fixed at the temperature measurement position.
It will be appreciated that during rotation of the threaded fastener 131, the threaded fastener 131 will contact the mounting member 31 to generate friction, and the mounting member 31 will tend to rotate in the same direction as the threaded fastener 131 when driven by the friction. The temperature sensor 10 located on the mounting base 30 also tends to rotate with the mounting base 30, thereby pulling the adaptor 20 connected to the temperature sensor 10. As such, looseness or even disengagement may occur between the connection of the adapter 20 to the temperature sensor 10 and the connection of the adapter 20 to the device receiving the data signal, thereby causing the temperature sensor 10 to fail to transmit the temperature signal data through the adapter 20.
The stopper 32 protrudes from the mounting member 31, and the stopper 32 is for stopping engagement with other components in the battery 100 in the rotational direction of the threaded fastener 131.
The stopper may be engaged with other components in the battery 100 after the stopper 32 moves a small distance, or the stopper 32 may be engaged with other components in the battery 100 while the mount 31 is in contact with the temperature measurement position.
That is, one side surface of the stopper 32 in the rotational direction of the threaded fastener 131 can abut against other components in the battery 100 in the rotational direction of the threaded fastener 131 by the rotational tendency of the mount 31, thereby suppressing the further rotational tendency of the mount 31.
According to the temperature sampling structure 140, the stopper 32 is arranged on the mounting piece 31, so that the restrained mounting piece 31 generates a rotating movement trend in the process of mounting the threaded fastener 131, the pulling acting force of the adapter piece 20 in the process of mounting the threaded fastener 131 is reduced, the risk that the electrical connection of the adapter piece 20 is poor in contact or even fails due to rotation is reduced, the connection stability of the temperature sampling structure 140 is improved, and the assembly efficiency is improved.
In some embodiments, referring to fig. 3 and 4, the mounting member 31 is plate-shaped. Meanwhile, the contact area between the mounting piece 31 and the temperature measuring position is increased under the condition that the volume of the mounting piece 31 is fixed, so that the friction between the mounting piece 31 and the temperature measuring position is increased while the heat conduction efficiency is provided, and the rotation trend of the mounting piece 31 is well restrained.
In some embodiments in which the mount 31 is plate-shaped, referring to fig. 3 and 4, the through hole 31a penetrates the mount 31 in the thickness direction of the mount 31. Thus, the size of the through hole 31a is advantageously shortened, and the difficulty in manufacturing the through hole 31a is simplified.
It is understood that the penetrating direction of the through hole 31a is a straight line direction so that the threaded fastener 131 passes through the through hole 31a.
In some embodiments, referring to fig. 3 and 4, the protruding direction of the stopper 32 is the same as the extending direction of the through hole 31 a.
In this way, in the process of contacting the mounting member 31 with the temperature measurement position along the extending direction of the through hole 31a, the stop member 32 is matched with other parts in the battery 100 synchronously, so that the mounting step is simplified; meanwhile, the projection area of the mounting seat 30 perpendicular to the extending direction of the through hole 31a is reduced, so that the mounting of the mounting seat 30 in the battery 100 is facilitated, and the suitability of the temperature sampling structure 140 is improved.
In some embodiments, referring to fig. 3 and 4, the stopper 32 and the temperature sensor 10 are located at opposite sides of the extending direction of the through hole 31a, respectively. That is, the temperature sensor 10 is away from the side of the mounting member 31 that is in contact with the temperature measuring position, thereby reducing the probability of collision of the temperature sensor 10 with other components in the battery 100 during the mounting of the fixed mounting member 31, and at the same time, facilitating the subsequent observation of the state of the temperature sensor 10 for repair, test, and maintenance.
The specific number of the stoppers 32 is not limited, and may be one or a plurality.
The number of the stoppers 32 is plural, and on the one hand, the contact area of the stoppers 32 in the rotational direction along the threaded fastener 131 can be increased by the plural stoppers 32, and the movement tendency of the mounting member 31 to be relatively rotated can be suppressed better; on the other hand, the stop fit of the stop member 32 is facilitated to be realized at one time in the process of assembling the mounting member 31, the assembling step is simplified, and the assembling efficiency is improved.
